Abstract
Description
- The present invention refers to a sprayer for liquids, in particular a pump sprayer operated manually by means of a trigger lever, with an integrated USD (upside down) device which allows delivery of the product even when the sprayer is in an upside-down position.
- A sprayer generally comprises a main body provided with a base with a threaded ferrule or with a bayonet coupling to be applied to the mouth of a container for liquids, a delivery nozzle from which the liquid is sprayed, a trigger lever that can be manually operated by the user, and a pump that can be operated by the trigger lever to draw the liquid from the container by means of a dip tube and spray it through the delivery nozzle.
- The pump has a piston acting in a chamber formed in the body of the sprayer. The body of the sprayer further comprises an inlet duct that puts the inside of the fluid container into communication with the pump chamber and an outlet duct that puts the pump chamber into communication with the sprayer nozzle. Within or immediately upstream of the pump chamber there is a fluid suction and delivery valve adapted to allow the fluid to be sucked selectively in a one-way manner from the container to the pump chamber and delivery of the fluid from the pump chamber towards the delivery nozzle.
- A sprayer with a built-in USD device, to which the invention refers, allows dispensing of the liquid even in an upside-down position, that is, with the dip tube protruding beyond the liquid held in the container, when said container is in an upside-down position.
- Examples of sprayers of this type are described for example in EP 968767 A1, EP 867229 A1 and WO 2006/101388 A1.
- The sprayers described in the cited documents have two main drawbacks:
- 1. Numerous additional components are necessary for operation in an upright and upside-down position, with a consequent increase in the manufacturing cost of the sprayer;
2. A USD valve assembly is present in the area beneath the body of the sprayer which requires a dedicated filling and assembly line (container—product—sprayer), or else the dimensions of these sprayers in said area are such as to require often costly modifications to the filling lines already installed. - Object of the invention is to eliminate the above mentioned drawbacks, by providing a sprayer with a USD device, that is, capable of operating even in an upside-down position, with the components necessary to perform this function reduced to a minimum, and thus limiting the increases in the cost of the product.
- Another object of the invention is that of providing such a sprayer that is able to adapt to existing filling lines without requiring economically significant changes.
- Yet another object of the invention is that of providing such a sprayer that is simple and cheap in design and can if necessary be transformed into a sprayer without a USD function.
- The above mentioned objects are achieved by the sprayer according to the invention which presents the features of appended independent claim 1.
- Advantageous embodiments of the invention are set forth in the dependent claims.
- Essentially, in the sprayer according to the invention, there is provided behind the pump body a cavity or cylindrical chamber communicating at the bottom with the channel for sucking the liquid from the container through the dip tube, and having in its side wall slots which put it into communication with the inside of the container.
- In this cylindrical cavity, which is closed at the top, there is housed a ball, which in normal conditions of use of the sprayer (Up position) is disposed on a conical surface provided near the bottom of the cavity, closing the duct communicating with the liquid suction channel, and thus preventing the liquid drawn from the container during operation of the pump from being able to flow into the cylindrical cavity.
- In the upside down operating condition (Down position) the ball moves to the other end of the cylindrical cavity, freeing the suction channel and allowing the liquid to flow out therefrom through the above mentioned slots provided in the side wall of the cylindrical cavity, following the depression created by operation of the pump.
- Further characteristics of the invention will be made clearer by the detailed description that follows, referring to purely exemplary and therefore non limiting embodiments thereof, illustrated in the appended drawings, wherein:
-
FIG. 1 is median sectional view of a sprayer according to the invention in the upright operating condition (Up position); -
FIG. 2 is view like that ofFIG. 1 with the sprayer in the upside-down operating condition (Down position); -
FIGS. 3 and 4 are axonometric views of the sprayer according to the invention, without the covering cap and with parts in a cutaway view, shown in the upright and upside-down position, respectively; -
FIG. 5 is a view like that ofFIG. 1 , showing a different closing modality for the chamber with USD device; -
FIG. 6 is a view likeFIG. 1 , in which the USD has been eliminated. - The appended figures show a sprayer structure as described in European patent EP 1585602 in the name of the same applicant to which reference can be made for greater details on operation of the sprayer, which will be described herein only summarily.
- The sprayer according to the invention, designated as a whole with
reference numeral 10, comprises abody 11 closed by acovering cap 12. - A
fixing ferrule 11, having an inner thread suitable to engage with an outer thread of the mouth of a container (not shown), suitable for containing a liquid such as, for example, household cleaning liquids, is rotatably mounted at a base of thebody 10. Of course, fixing of the sprayer on the container can also take place in a different manner, for example by means of a bayonet coupling. - The
body 11 of the sprayer is substantially L-shaped and ends in aspray nozzle 16 with an opening from which the liquid is dispensed. - A
trigger lever 17, hinged at oneend 18 to thebody 11 and in anintermediate portion 19 to thestem 20 of aplunger 21, slidable in achamber 22 of apump body 23, is provided for operating the sprayer. A hole for entry of theliquid 24, in communication with the inside of the container through adip tube 25, and anoutlet hole 26, in communication with thespray nozzle 16, through avertical duct 27 and ahorizontal duct 28, are formed in the rear wall of thechamber 22. - The aforesaid liquid inlet and
outlet holes dome portion 31 and a frustoconical tang of a one-way suction anddelivery valve 30. - Operation of the one-way valve, described better in the aforementioned patent EP 1585602 is fairly intuitive.
- On pressing the
trigger lever 17, the liquid in thechamber 22 of the pump exerts pressure against thevalve 30, deforming thefrustoconical tang 32 and then exiting through theoutlet hole 26 to travel towards thespray nozzle 16. - When the
trigger lever 17 is released and returns the resting position through the action of elastic means not described, theplunger 21 creates a vacuum in thechamber 22, freeing theinlet hole 24, as shown inFIG. 1 , causing the liquid sucked from the container to flow into thechamber 22. - What is described thus far is to be considered known from the aforesaid patent EP 1585602.
- According to the invention, to make the sprayer thus far described into a sprayer of the USD (Up-Side-Down) type, there is provided behind the pump body 23 a
cylindrical chamber 40, integral with thepump body 11 which extends parallel to and in contact with thevertical portion 27 of the liquid outlet duct. - The
chamber 40 is closed at the top by astopper 41, which in the embodiment shown inFIG. 1 also closes thevertical portion 27 of the liquid outlet duct. - Of course other solutions can be provided to close the
chamber 40, and a possible alternative is shown inFIG. 5 , in which thestopper 41 is formed integrally with theclosing cap 12. - In the
chamber 40 there is disposed aball 42, preferably of plastic material, which in normal operating conditions of the sprayer (Up position—FIG. 1 ) is tightly housed on aconical seat 43, closing ahole 44 provided on the bottom of said chamber, which puts it into communication with theinlet hole 24 of the pump chamber, through a shorthorizontal duct 45. - In the
wall 46 of thechamber 40, above theball 42, there are provided slots orwindows 47, visible inFIGS. 3 and 4 which put thechamber 40 directly into communication with the inside of the liquid container through respective secondary channels. - Operation of the sprayer in the Up and Down position is as follows.
- In the Up position (
FIG. 1 ), theball 42 is pressed against theconical surface 43 by the pressure difference that is created during the suction step, together with the weight of said ball, thus keeping thehole 44 on the bottom of thechamber 40 closed and allowing normal operation of the sprayer, with suction of the liquid from the inside of the container through thedip tube 25. - In the Down position (
FIGS. 2 and 4 ) theball 42 falls by gravity to the other end of thechamber 40, where thestopper 41 is provided, freeing thehole 44 and putting thewindows 47 into communication with theinlet hole 24 of the pump through theduct 45. - In this position the
chamber 40 is flooded with the liquid that enters through thewindows 47 and is then sucked by vacuum into thechamber 22 of the pump following operation of thetrigger lever 17 during the return step of theplunger 21, through the effect of elastic means not described. - When the sprayer is brought back to the normal operating condition (Up position), the liquid contained in the
USD chamber 40 falls back into the container, theball 42 is positioned on theconical seat 43 again and the sprayer can operate normally by sucking the liquid from the container through thedip tube 25. - Since the
windows 47 in the wall of thechamber 40 are positioned higher up than theball 42, thechamber 40 is at atmospheric pressure, which is the same as the pressure inside the container. In fact, in a per se known manner, the pressure inside the container is restored to atmospheric pressure at each operation of thetrigger lever 17, through anair hole 50 which is situated at the base of thepump body 23 housing theplunger 21. Thehole 50 puts the inside of the container into communication with the outside only when thetrigger lever 17 is pressed. - From this description the advantages of the sprayer according to the invention are evident, in that with minimal modifications it allows the USD function to be used, without requiring any modification to the filling lines.
- As confirmation of the simplicity and versatility of the sprayer according to the invention,
FIG. 6 shows a version in which the USD function has been eliminated, simply by closing thehole 44 provided on the bottom of thechamber 40 and thewindows 47 provided on thewall 46 of said chamber, during moulding. - As stated, the
ball 42 is preferably of plastic material, essentially like the other components of the sprayer, so as to allow complete recycling thereof. Obviously it is not ruled out that the ball might be of metal material if the end use of the sprayer so requires. - Of course the invention is not limited to the particular embodiments previously described and illustrated in the appended drawings, but numerous modifications of detail within the reach of a person skilled in the art can be made thereto without thereby departing from the scope of the invention as set forth in the appended claims.
